分析了同步带齿与轮齿齿形参数在传动中产生的多边形效应基础上，建立了同步带传动精度计算模型，由此分析了紧迫长度、带与轮齿形参数对传动精度的影响，并对梯形齿、双圆弧齿同步带传动精度进行了计算和比较，为同步带在精密设备上的应用提供了计算依据。

According to transmissiorl characteristics of synchronous belt, transmissionprecision calculation model is established, on the basis of analyzing polygon effect of synchronous transmission produced by tooth outlinee parameter of belt and pulley. At the sametime, effect of analyzing tighten side length and tooth profile parameter of belt and pulley totransmission precision is done. The paper calculates and compares transdrission precision oftrapezoid and double curve synchronous belt and provides calculation foundation for applyingof precisi0n equipment.
